Many people expect a lot of Windows 8 news to be announced in September. That's when Microsoft plans to hold its new BUILD developer conference. This year the event is being held at the Anaheim Convention Center in Anaheim, California from September 12 to September 16. However if you were thinking of attending the show, you are too late: As ZDNet.com reports, the BUILD conference is now sold out.

The event itself is a brand new one for Microsoft and ZDNet says that it will be a replacement, at least for 2011, for two previously held conferences by the company: the Professional Developers Conference and the Windows Hardware Engineering Conference (WinHEC). Currently the web site for BUILD has only a bare bones agenda posted up which may mean that Microsoft has quite a bit of stuff planned that it doesn't want to reveal yet.

Previous rumors have suggested that Microsoft will use the BUILD conference as its excuse to release a true beta version of its Windows 8 operating system to developers who attend the event. The next version of Microsoft's PC OS is currently believed to be targeted for a final release sometime in 2012. While the BUILD conference is supposed to be a Windows based event its possible that Microsoft could also have sessions and info about other parts of the business including Windows Phone 7 and Xbox. ZDNet reports that Microsoft is also planning to hold one day developer events in cities around the world around the time of the BUILD conference.
